Updated October 22, 2026 · 2 min read [Open Workflows ↗](https://app.oneform.si/workflows?help=workflow-triggers) The trigger is what starts a workflow. You choose it under **Starts when** at the top of the workflow editor. Each workflow has one trigger and belongs to one form, so it only starts for that form's clients. ## Choose a trigger 1. Open the workflow from [Workflows](https://app.oneform.si/workflows). 2. At the top, click the event under **Starts when**. 3. Pick a trigger from the list. The line under it says exactly when it starts. A form's Default workflow always starts with **Form is submitted**, so you can't change its trigger. ## Every trigger | Trigger | Starts when | | --------------------------- | -------------------------------------------------------------------------------------------------------------------------- | | **Form is submitted** | Someone finishes the form. | | **Form is left unfinished** | Someone answers some questions, then stops for an hour without submitting. It starts once, and stops if they finish later. | | **Report is approved** | A reviewer approves the report. | | **Report is sent** | The report email goes out. | | **Report is opened** | The client first opens the report email or their report page. Once per report. | | **Payment received** | Someone pays for a report or a consultation. | | **Call is booked** | Someone books a call on the form's thank-you screen. Once per submission. | | **Call is rescheduled** | A booked call moves to a new time, by the client or your team. Each time it moves. | | **Call is cancelled** | A booked call is canceled, by the client or your team. | | **Lead becomes Hot** | A person's lead score reaches Hot for the first time. Once per person. | ## Good to know - **The trigger decides which actions fit.** The action picker only offers actions that make sense for the trigger. For example, **Draft the report** only fits **Form is submitted**, and a confirmation email doesn't fit **Lead becomes Hot**. If you change the trigger later, an action that no longer fits says so, and the workflow can't be turned on until you remove it. - **What you can insert follows the trigger.** **\+ Insert answer** offers call details for the call triggers, payment details for **Payment received**, and the last question answered for **Form is left unfinished**. - **Unfinished forms are tracked only while a workflow needs them.** Once a **Form is left unfinished** workflow is on, the form saves answers as people go. A run starts at most once a week for the same email address. See [Unfinished forms](https://oneform.si/help/share/unfinished-forms/). - **Hot leads need lead scoring.** **Lead becomes Hot** uses the score on the **Leads** page and needs a plan with full Leads. The score is checked when someone submits a form, or opens or clicks an email. See [Hot lead alerts](https://oneform.si/help/responses-and-leads/hot-lead-alerts/). - **Calls come from the thank-you screen.** The call triggers start for calls booked after someone fills in this form. See [Offer a call after a form](https://oneform.si/help/bookings/offer-a-call-after-a-form/). ## Why didn't my workflow start? - **It isn't on.** Only workflows marked **On** start. Drafts and paused workflows don't. - **It's for another form.** Each workflow belongs to one form. The Workflows page lists your workflows under the form they belong to. - **It already ran for that person or report.** **Report is opened**, **Call is booked** and **Lead becomes Hot** start only once for the same report, submission or person. - **They came back and finished.** **Form is left unfinished** doesn't start, or stops, when the same person submits the form.
